HEATING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 492,431, dated February2Q, 1893.

Application filed .Tune 2, 1892i To all whom it may concern.: 1

Beit known that I, WILLIAM RENNYsoN, a citizen of the United States,residing at- Norristown, in the cou nty of Montgomery and' State ofPennsylvania, have invented certain `new and useful Improvements inHeating Attachments, of which the following is a specification,reference being had therein to the accompanying drawings, in which-Figure 1 represents a side elevation of one form of my device applied tothe globe of a gas burner; Fig. 2 a vertical section `of the same; Fig.3 a horizontal section of a portion of. the cylinder showing the mannerof connecting its transparent sections; Fig. 4

. a' plan of the base-plate or ring;` Fig; 5 la side View of the`complete device showing a modi- `iied form of the supporting devices;Fig. 6 a similar view showing still another form of supporting devices,used in connection with a lamp chimney; Fig. '7 a vertical sectionshowing a modified means for attaching the parts of the device together;Fig.` 8 a side 4elevation showing another device for supv wherein aglobe or reservoir is detachably supported above the flame of a gas jetor oil lamp to receive and temporarily conline the hot gases as theyascend from the fiame and radiate them downwardly and outwardly into theroom whereby the heating and lighting capacity of the flame are greatlyincreased; 4 and the objects of the present invention are to render thedevice lighter, cheaper, and simpler in construction, more efficient inaction, more ornamental in appearance, and more easily taken apart fortransportation and cleaning purposes7 as will more fully hereinafter bedescribed.

Referring to the drawings by letters, a designates the vertical cylinderof the heating device, which cylinder tapers toward its upper end and isconstructed preferably of a series of vertical sections of mica securedtogether at their overlapped edges by small Serial No. 435,322. (Nomodel.)

staples ct. The upper and lower edges of the cylinder are bound withstrips of metal a which extend entirely around the cylinder and serve togive strength and rigidity to it and also to form a close joint with theadjacent parts of the device. Openings a2 are formed in this 4cylinderif desired for the purpose of throwing out heatin radial currents, butas the device will probablyoperate equally well without these openingsthey may be omitted if desired.

The letter b indicates the conical top or cover which is removablysecured tightly over the upper end of the cylinder by any suitable meansand which is constructed of segmental plates of mica secured together attheir overlapped edges by small staples and also at` the apex of thecone by a small clamp b', this cap or cover preferably having its edgeextended out a short distance beyond the cylinder, this projecting edgeserving to collect and radiate the ascending heat currents and also toadd to the appearance of the device. This cap is preferably secured tothecylinder by long flexible strips b Whose upper ends are secured tothe inside of the cap and whose lower ends extend down through thecylinder and are passed through slits in a metal or glass. disk or ringc and bent up against the lower side of the same, thereby serving toremovably but securely clamp the three pa-rts of the device together.This disk is provided with a central opening for the products ofcombustion to pass up into the cylinder and it is made of greater widththan the cylinder in order that it may be applied to the various sizesand styles of globes.

To detach the parts of the device it is simply necessary to straightenthe bent ends of the metal strips, as shown in dotted lines in Fig. 8whereupon the disk and cylinder may be readily slipped oft the strips.Ineans of detaching the parts enables them to be more compactly packedfor shipment and also enables the parts to be cleaned more readily. Theconical shape of the cylinder and the cap not only enables these partsto be cleaned more readily, but also permits them to be packed onewithin the other for transportation, which are important advantages. Ipreferably construct the cylinder This readyand cap of mica as thatmaterial isligh'dand cheap as 'Wellas' ornamental, but it is evidentthat they may be constructed of glass or other materials if founddesirable. If desired, to prevent the rings slipping off the globe, de-

pending stops c maybe secured on its under;
